Latest Patents
Hokushin holds a patent for a "Thin-film magnetic head and method of manufacturing same, head gimbal assembly and hard disk drive." This patent describes a method of forming a track width defining layer that includes a magnetic pole portion. The process begins with the formation of a base film on a write gap layer, which consists of a first layer made of a magnetic material with a saturation magnetic flux density of 1.8 T or more. A second layer, made of a magnetic material containing Fe or Ni as a main component and without Co, is then formed on the first layer. A frame with an opening matching the track width defining layer is created on the second layer, followed by the formation of the track width defining layer through electroplating, using the base film as an electrode.
